BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to the field of remote data collection.More specifically, embodiments of the present invention relate to therequesting, transmitting, collecting, storing, reviewing, and publishingof remotely collected data as supplied by an electronic device, e.g., acomputer system, a portable computer system, a palmtop computer system,or any other hand-held electronic device that utilizes a display screen,such as a cell phone, a pager, etc.

2. Related Art

Over the last couple of decades, peer-to-peer and server-clientcomputing have been extensively utilized. For example, in the late1980s, Sun Microsystems' operating system allowed networked computers toshare their disk storage across the network. In essence, this providedfor sharing a resource, in this case disk storage, amongst manycomputers. A more recent example is the Napster music-sharing system. Inthe Napster system, music files are stored across a very large number ofpersonal computers, and users can copy a music file from many differentplaces. Once again, the shared resource is disk storage.

Another example of shared storage resources is provided by Gnutella.From their website at www.gnutella.wego.com: “Gnutella is afully-distributed information-sharing technology”; and “when you runGnutella software and connect to the Gnutella Network, you bring withyou the information you wanted to make public. That could be nothing, itcould be one file, a directory, or your entire hard drive.” Essentially,Gnutella provide a means for the user of a personal computer to shareany part of the contents of his hard disk with other users on theInternet.

Networked computers have also shared computational resources. A largecomputational task, such as the factoring of a very large number, can besplit into a plurality of smaller tasks, and each smaller task isassigned to a separate computer. A practical example of sharedcomputational resources is the SETI@home project (having a web page athttp://setiathome.ssl.berkeley.edu/), where radioastronomy data iscollected at a central server, and subsets are parceled out to personalcomputers over the Internet. The personal computers search the subsetsfor potential extraterrestrial signals.

As the components required to build a computer system have reduced insize, new categories of electronic devices and computer systems haveemerged. One of the new categories of computer systems is the “palmtop”computer system. A palmtop computer system is a computer that is smallenough to be held in the hand of a user and can therefore be“palm-sized.” Most palmtop computer systems are used to implementvarious Personal Information Management (PIM) applications such as anaddress book, a daily organizer (calendar, datebook, etc.) andelectronic notepads, to name a few. Palmtop computers with PIM softwarehave been know as Personal Digital Assistants (PDAs). Many PDAs have asmall and flat display screen associated therewith. Also, PDAs are nowincluding a wireless connection to a network, including the Internet,making them candidates for resource sharing. PDAs are generally designedto be light, inexpensive, and power efficient, and this makes them poorcandidates for sharing either data storage or computational resources.

PDAs are now including various peripheral input devices, such asmicrophones, global positioning systems (hereinafter, GPS), and cameras.Since a PDA is, basically, a computer, the numerous types of otherinput/output devices that have been interfaced to a computer can beinterfaced, or incorporated into, a PDA. Such other input/output devicesinclude: video cameras, altimeters, and seismic activity recorders.

In addition to PDAs, other portable electronic devices have displayscreens and wireless network connections, such as cell phones,electronic pagers, remote control devices and other wireless portabledevices. All of these devices have been adapted to display short listsof information on the display screens to help the user organize anddisplay information, e.g., phone records.

User convenience is a very important factor for portable electronicdevices. Typically, portable electronic devices are employed while theuser is on the run, e.g., in business meetings, on business travel,personal travel, in a vehicle, on foot, etc. Because the user may beoccupied or busy while using the portable electronic device, the numberof user steps or user tasks required in order to access information froman electronic device (or to store information into the electronicdevice) is crucial for producing a commercially successful and usefulproduct. That is, the more difficult it is to access data from anelectronic device or input data into an electronic device, the lesslikely the user will perform those tasks. Likewise, the easierinformation is to obtain, the more likely the portable electronic devicewill be used to obtain that information and the more likely the portableelectronic device will become a part of the user's everyday activities.For electronic devices to be used for resource sharing, the sharing mustbe very convenient for the user.

The prior art for remote data gathering includes various dedicateddevices. An example is a remote weather station for collectingtemperature, rainfall, barometric pressure, and other weather-relateddata. Another example is a location-tracking device attached tomigratory animals, used to study animal migration patterns.Unfortunately, present devices for gathering geographically distributeddata are dedicated-purpose devices, and are not appropriate for use inthe general population of people. Hence, present-day devices are notuseful for tasks such as: gathering automobile traffic conditions;opinion polling; and on-the-spot supplying of news information.

SUMMARY OF THE INVENTION

Accordingly, embodiments of the present invention provide a systemcomprising one or more computer servers and one or more electronicdevices having a method for gathering, collecting, and supplyinggeographically distributed data. Therefore, the present invention allowsfor: a server to gather geographically distributed data from one or moreelectronic devices; a server to collect responses from users ofelectronic devices; and users of electronic devices to supplygeographically distributed data to a server. In other words, the presentinvention provides for a new type of shared resources: geographicallydistributed data and input from the users who are geographicallydistributed. The present invention provides these advantages and othersnot specifically mentioned above but described in the sections tofollow.

The present invention provides four modes of collecting data: (1)gathering geographically distributed data in a server-commanded mode,accomplished by a computer server commanding electronic devices tocapture and transmit data, such that the user of the electronic deviceneed not participate in the capturing or transmitting, and is, thereforetransparent to the user; (2) collecting user responses in aserver-initiated mode, accomplished by a computer server requesting theuser of an electronic device to input data, the data then transmitted tothe server; (3) supplying geographically distributed data in auser-initiated mode, accomplished by a user capturing data with anelectronic device, the electronic device transmitting the data to acomputer server, and the computer server then storing, selling, orpublishing the data; and (4) gathering a body of geographicallydistributed data in a user-controlled mode, accomplished by the user ofan electronic device instructing his electronic device to automaticallycollect input data, the data then transmitted to a computer server.

The first mode, gathering a body of geographically distributed data in aserver-commanded mode, is useful for situations where the user of theelectronic device need not be bothered to respond. For example, assumingthere are thousands of users with electronic devices in their cars asthey commute to work (with the electronic devices turned on, enabled toparticipate in the gather of data, and equipped with a GPS), a computerserver can query all the electronic devices for location and speed inorder to generate a overall picture of traffic conditions. This overallpicture could then be sent to the users, published on the Internet, orbroadcast on television or radio. Similarly, temperature, sound, andeven seismic activity could be gathered this way.

For gathering a body of geographically distributed data from a pluralityof electronic devices in a server-commanded mode, for a particularembodiment of the invention, a computer server and an electronic deviceperform the following steps: (1) the computer server selects anelectronic device from which to gather data; (2) the computer serverrequests the current location of the electronic device, and, if it doesnot already know the types of geographically distributed data that theelectronic device can collect, requests this information also; (3) theelectronic device receives the request and transmits the requestedinformation; (4) based on this information, the computer server decideswhether the electronic device is appropriate to contribute to the bodyof data, and skips further communication with the electronic device ifit is not appropriate to gather the needed data, the electronic devicecan be inappropriate due to its location; (5) the computer servertransmits a command to the electronic device to capture particulartype(s) of data; (6) the electronic device receives the command tocapture the data; (7) the electronic device captures the geographicallydistributed data; (8) the electronic device transmits the captured datato the computer server; (9) the computer server receives the captureddata; and (10) the computer server stores or processes the receiveddata; and (11) the computer server credits value to an accountcorresponding to the electronic device.

For gathering data in a server-commanded mode, additional steps may alsobe of significant value: (A) the electronic device sends a verifiableidentity code to the computer, and the computer server uses this code toverify the identity of the transmitting device, thereby avoidingsecurity breaches; (B) the computer server credits value to an accountcorresponding to selected electronic device, thereby compensating theuser of the electronic device for the use of the electronic device; (C)encrypting and decrypting any data so as to keep it private; and (D) thecomputer server maintaining a list of active electronic devices, addingand subtracting electronic devices to/from the list as userslogon/logoff or power-on/power-off their electronic devices.

The second mode, collecting user responses in a server-commanded mode,is useful for situations where input from the user is desired. Forexample, marketing surveys can be performed where it is up to the useras to whether he will respond. A particularly useful example is therequesting of opinions based on geographic location. For example, theuser could be surveyed when leaving a particular type of restaurant(such as McDonald's) as to his experiences. Similarly, a survey could betaken of users located at a particular sporting event (such as the SuperBowl). These surveys could be accompanied by a sales pitch for aparticular company or product. If a user participated in a surveycollecting responses from people who just ate at McDonald's, anadvertisement or coupon for Burger King could be sent to the user if hissurvey indicated any dissatisfaction. Hence, marketing data and salescould be done in a distributed fashion.

For collecting user responses in a server-initiated mode, for aparticular embodiment of the invention, a computer server and anelectronic device perform the following steps: (1) the computer serverselects the electronic device, the electronic device having acorresponding user; (2) optionally, the computer server requests thecurrent location of the electronic device (needed if the responses aregathered according to current location), the electronic device transmitsits current location to the computer server, and the computer serverskips further communication with the electronic device if the electronicdevice's current location is not within a predetermined geographic area;(3) the computer server transmits a command to cause the electronicdevice to notify its user that a response is requested; (4) theelectronic device receives the command to solicit a user response fromthe user; (5) the electronic device notifies the user that a response isrequested; (6) the computer server transmits the information to whichthe user of the electronic device is to respond; (7) the electronicdevice receives the information to which the user of the electronicdevice is to respond; (8) the electronic device receives the userresponse from the user; (9) the electronic device transmits the receiveduser response; (10) the computer server receives the user response fromthe electronic device; and (11) the computer server stores or processesthe user response;

For collecting user responses in a server-initiated mode, additionalsteps may also be of significant value: (A) the electronic device sendsa verifiable identity code to the computer, and the computer server usesthis code to verify the identity of the transmitting device, therebyavoiding security breaches; (B) the computer server credits value to anaccount corresponding to the selected electronic device, therebycompensating the user of the electronic device for his response; (C)encrypting and decrypting any data so as to keep it private; and (D) thecomputer server maintaining a list of active electronic devices, addingand subtracting electronic devices to/from the list as userslogon/logoff or power-on/power-off their electronic devices.

The third mode, supplying geographically distributed data in auser-initiated mode, is useful for situations where the user of theelectronic device wants to capture data that is local to him anddistribute it to a wider audience. For example, the user of anelectronic device could be the witness of an accident, and use hiselectronic device to capture video images (assuming the electronicdevice includes a video capture mechanism), upload them immediately to acomputer server, and then the computer server can distribute or publishthe video images as desired. This mode of operation makes the user of anelectronic device a roving reporter. The invention also includes methodsfor reviewing the submitted data before it is distributed or published.The review is important to filter out inappropriate, uninteresting, andredundant news.

For supplying geographically distributed data in a user-initiated mode,for a particular embodiment of the invention, a computer server and anelectronic device perform the following steps: (1) the electronic devicereceives a command from the user to capture data; (2) the electronicdevice captures the data; (3) the electronic device transmits thecaptured data; (4) the computer server receives the suppliedgeographically distributed data from the electronic device; (5) thecomputer server stores the received geographically distributed data; (6)the computer server makes the stored geographically distributed dataaccessible to a predetermined set of editors; (7) the computer serverreceives approval to publish from at least one of the editors; (8) thecomputer server credits value to an account corresponding to theelectronic device; and (9) the computer server credits value to anaccount corresponding to the participating editors.

For supplying geographically distributed data in a user-initiated mode,additional steps may also be of significant value: (A) the electronicdevice sends a verifiable identity code to the computer, and thecomputer server uses this code to verify the identity of thetransmitting device, thereby avoiding security breaches; (B) encryptingand decrypting any data so as to keep it private; and (C) the computerserver maintaining a list of active electronic devices, adding andsubtracting electronic devices to/from the list as users logon/logoff orpower-on/power-off their electronic devices.

The fourth mode, gathering a body of geographically distributed data ina user-controlled mode, is useful for situations where the user of theelectronic device need not be bothered to respond, but has theelectronic device automatically transmit the gathered data withoutreceiving a command from the server. For example, assuming there arethousands of users with electronic devices in their cars as they commuteto work (with the electronic devices turned on, enabled to participatein the gather of data, and equipped with a GPS), the entire set ofelectronic devices periodically transmit their location and speed inorder to generate an overall picture of traffic conditions. This overallpicture could then be sent to users, published on the Internet, orbroadcast on television or radio. Similarly, temperature, sound, andeven seismic activity could be gathered this way.

For gathering a body of geographically distributed data from a pluralityof electronic devices in a user-controllable mode, for a particularembodiment of the invention, a computer server and an electronic deviceperform the following steps: (1) if the electronic device is enabled forgathering data, the electronic device waits for the correct time tocapture data; (2) the electronic device captures the types of data asselected by the user; (3) the electronic device transmits the captureddata to the computer server; (4) the computer server receives thecaptured data; (5) the computer server verifies the identity of thetransmitting electronic device; (6) the computer server stores orprocesses the received data; and (7) the computer server credits valueto an account corresponding to the transmitting electronic device.

In all four of the above described modes of collecting geographicallydistributed data, the type of data can be one or more of the following:position, velocity, acceleration, temperature, altitude, air pressure,direction, audio, video, still pictures, vibration, and time of day. Inaddition to these, any other type of data that can be captured by acomputer can be collected by the above methods.

Exemplary Palmtop Computer System Platform

The processes of the present invention described herein are particularlyapplicable to portable electronic devices that have display screens andthat include a connection to a wireless communication network. Thesedevices include, for instance, cell phones, pagers and portable computersystems. Although applicable across a wide variety of platforms anddevices, the present invention is described herein by example withrespect to a portable computer system.

FIG. 1 illustrates an exemplary networked system 50 that can be used inconjunction with an embodiment of the present invention. System 50 isexemplary only and comprises a host computer system 56 which can eitherbe a desktop unit as shown, or, alternatively, can be a laptop system58. Optionally, one or more host computer systems can be used withinsystem 50. Host computer systems 58 and 56 are shown connected to acommunication bus 54, which in one embodiment can be a serialcommunication bus, but could be of any of a number of well knowndesigns, e.g., a parallel bus, Ethernet Local Area Network (LAN), etc.Optionally, bus 54 (or a separate communication channel) can providecommunication with the Internet 52 using a number of well knownprotocols.

Importantly, bus 54 is also coupled to a cradle 60 (or cable dock) forreceiving and initiating communication with an exemplary palmtop(“palm-sized”) portable computer system 100. Cradle 60 provides anelectrical and mechanical communication interface between bus 54 (andanything coupled to bus 54) and the computer system 100 for two waycommunications. Computer system 100 may also contain a wireless infraredcommunication mechanism 64 for sending and receiving information to orfrom other devices.

FIG. 2A is a perspective illustration of the top face 100 a of oneembodiment of the palmtop computer system. The top face 110 a contains adisplay screen 105 surrounded by a bezel or cover. A removable stylus 80is also shown. The display screen 105 contains a transparent touchscreen (digitizer) able to register contact between the screen and thetip of the stylus 80. The stylus 80 can be of any material to makecontact with the screen 105. As shown in FIG. 2A, the stylus 80 isinserted into a receiving slot or rail 350. Slot or rail 350 acts tohold the stylus when the computer system 100 a is not in use. Slot orrail 350 may contain switching devices for automatically powering downand automatically power up computer system 100 a based on the positionof the stylus 80. The top face 100 a also contains one or more dedicatedand/or programmable buttons 75 for selecting information and causing thecomputer system to implement functions. Other buttons (icons) can beimplemented within a silk screen layer material 84 on which regions 106a and 106 b reside. The on/off button 95 is also shown.

FIG. 2A also illustrates a handwriting recognition pad or “digitizer”containing two regions 106 a and 106 b. Region 106 a is for the drawingof alpha characters therein for automatic recognition (and generally notused for recognizing numeric characters) and region 106 b is for thedrawing of numeric characters therein for automatic recognition (andgenerally not used for recognizing numeric characters). The stylus 80 isused for stroking a character within one of the regions 106 a and 106 b.The stroke information is then fed to an internal processor forautomatic character recognition. Once characters are recognized, theyare typically displayed on the screen 105 for verification and/ormodification.

The digitizer 160 records both the (x, y) coordinate value of thecurrent location of the stylus and also simultaneously records thepressure that the stylus exerts on the face of the digitizer pad. Thecoordinate values (spatial information) and pressure data are thenoutput on separate channels for sampling by the processor 101 (FIG. 5).In one implementation, there are roughly 256 different discrete levelsof pressure that can be detected by the digitizer 106. Since thedigitizer's channels are sampled serially by the processor, the strokespatial data are sampled “pseudo” simultaneously with the associatedpressure data. The sampled data is then stored in a memory by theprocessor 101 (FIG. 5) for later analysis.

FIG. 2B illustrates the bottom side 100 b of one embodiment of thepalmtop computer system. An optional extendible antenna 85 is shown andalso a battery storage compartment door 90 is shown. A communicationinterface 108 is also shown. In one embodiment of the present invention,the serial communication interface 108 is a serial communication port,but could also alternatively be of any of a number of well knowncommunication standards and protocols, e.g., parallel, SCSI, Firewire(IEEE 1394), Ethernet, etc. In FIG. 2B is also shown the stylusreceiving slot or rail 350.

FIG. 2C illustrates a front perspective view of another implementation100 c of the palmtop computer system. As shown, the flat central area iscomposed of a display screen area 105 and a thin silk screen layermaterial portion 84. Typically, the silk screen layer material portion84 is opaque and may contain icons, buttons, images, etc., graphicallyprinted thereon in addition to regions 106 a and 106 b. The displayscreen area 105 and portion 84 are disposed over a digitizer.

FIG. 3 is an exploded view of the exemplary palmtop computer system 100.System 100 contains a front cover 210 having an outline of region 106and holes 75 a for receiving buttons 75 b. A flat panel display 105(both liquid crystal display and touch screen) fits into front cover210. Any of a number of display technologies can be used, e.g., LCD,FED, plasma, etc., for the flat panel display 105. In one embodiment,the display 105 is a flat panel multi-mode display capable of bothmonochrome and color display modes.

The touch screen can be a digitizer. A battery 215 provides electricalpower. Replaceable cells or rechargeable batteries can be used. Wellknown electronics coupled to the battery 215 can detect the energy levelof the battery 215. This information can be sampled by the computersystem 110 (FIG. 5) using well known techniques. The digitizer of FIG. 3can be implemented using well known devices, for instance, using theADS-7846 device by Burr-Brown that provides separate channels forspatial stroke information and pressure information. A contrastadjustment (potentiometer) 220 is also shown but can also be implementedelectronically, e.g., by software, (FIG. 2C) without any manual knob.On/off button 95 is shown along with an infrared emitter and detectordevice 64. A flex circuit 230 is shown along with a PC board 225containing electronics and logic (e.g., memory, communication bus,processor, etc.) for implementing computer system functionality. Thedigitizer pad is also included in PC board 225. A midframe 235 is shownalong with stylus 80. Optional position adjustable antenna 85 is shown.The midframe 235 contains the stylus receiving slot or rail 350.

An optional radio receiver/transmitter device 240 is also shown betweenthe midframe and the rear cover 245 of FIG. 3. The receiver/transmitterdevice 240 is coupled to the antenna 85 and also coupled to communicatewith the PC board 225. In one implementation, the Mobitex wirelesscommunication system is used to provide two way communication betweensystem 100 and other networked computers and/or the Internet via a proxyserver. In other embodiments, TCP protocol can be used.

FIG. 4 is a perspective illustration of one embodiment of the cradle 60for receiving the palmtop computer system 100. In other embodiments,cradle 60 is not a stand-up device but is rather part of a cableconnection between the palmtop computer system 100 and the desk topunit. Cradle 60 contains a mechanical and electrical interface 260 forinterfacing with serial connection 108 (FIG. 2B) of computer system 100when system 100 is slid into the cradle 60 in an upright position. Onceinserted, button 270 can be pressed to initiate two way communicationbetween system 100 and other computer systems coupled to serialcommunication 265.

FIG. 5 illustrates circuitry of palmtop computer system 100, some ofwhich can be implemented on PC board 225. Computer system 100 includesan address/data bus 99 for communicating information, a centralprocessor 101 coupled with the bus 99 for processing information andinstructions, a volatile memory 102 (e.g., random access memory RAM)coupled with the bus 99 for storing information and instructions for thecentral processor 101 and a non-volatile memory 103 (e.g., read onlymemory ROM) coupled with the bus 99 for storing static information andinstructions for the processor 101. Computer system 110 also includes anoptional data storage device 104 (e.g., thin profile removable memory)coupled with the bus 99 for storing information and instructions. Device104 can be removable. As described above, system 100 also contains adisplay device 105 coupled to the bus 99 for displaying information tothe computer user. PC board 225 can contain the processor 101, the bus99, the ROM 103 and the RAM 102.

Also included in computer system 110 of FIG. 5 is an alphanumeric inputdevice 106 which in one implementation is a handwriting recognition pad(“digitizer”) having regions 106 a and 106 b (FIG. 2A), for instance.Device 106 can communicate information (spatial data and pressure data)and command selections to the central processor 101. System 110 alsoincludes an optional cursor control or directing device 107 coupled tothe bus for communicating user input information and command selectionsto the central processor 101. In one implementation, device 107 is atouch screen device incorporated with screen 105. Device 107 is capableof registering a position on the screen 105 where the stylus makescontact and the pressure of the contact. The display device 105 utilizedwith the computer system 110 may be a liquid crystal device, cathode raytube (CRT), field emission device (FED, also called flat panel CRT) orother display device suitable for creating graphic images andalphanumeric characters recognizable to the user. In one embodiment, thedisplay 105 utilizes color sequential scanning but could also utilizecolor filters with subpixels.

Signal communication device 108, also coupled to bus 99, can be a serialport for communicating with the cradle 60. Device 108 can also includean infrared communication port.

FIG. 6 illustrates device 100 which contains several icons 270 printedon the silk screen layer. These icons, e.g., a home icon, a menu icon, acalculator icon and a finder icon, are user selectors and when tappedwith the stylus these icons cause certain applications to be executed orinvoke menu options within applications that are currently beingdisplayed. Also shown is a scroll selector 280. Scroll selector 280 hasan up button and a down button to cause list scrolling on the display105.

Also shown are two regions of digitizer 106 a and 106 b. Region 106 a isfor receiving user stroke data (and pressure data) for alphabetcharacters, and typically not numeric characters, and region 106 b isfor receiving user stroke data (and pressure data) for numeric data, andtypically not for alphabetic characters. Physical buttons 75 are alsoshown. Although different regions are shown for alphabetic and numericcharacters, the device is also operable within a single region thatrecognizes both alphabetic and numeric characters. It is appreciatedthat, in one embodiment, the digitizer region 106 a and 106 b areseparate from the display screen 105 and therefore does not consume anydisplay area. Also shown in FIG. 6 is the position of the stylusreceiving slot or rail 350.

Wirelessly Networked Distributed Resource Usage for Data Gathering inAccordance with Present Invention

FIG. 7 shows a system 400 including of a plurality of computer servers410 connected to a computer network 420, possibly the Internet or aprivate network. The servers 410 can be directly connected to a wirelesstransmitter 430, or can communicate with a wireless transmitter 430 overthe computer network 420. The transmitters 430 operate in full duplexmode, and can be standard cell phone transmission systems. FIG. 7 alsoshows a plurality of electronic devices 440, each including an antenna445 and the capability to communicate via a wireless communicationnetwork with the computer servers 430. Shown as attached to each of theelectronic devices 440 are a variety of input/output devices including:a GPS 450, a video camera 460, a microphone 470, and a temperaturesensor 480. Many other types of input/output devices are possible, asdescribed above. The input/output devices can be either attachments tothe electronic devices 440 (as implied in FIG. 7) or integrated into theelectronic devices themselves. The figure illustrates that eachelectronic device 440 can be equipped with different input/outputperipherals, and the present invention includes methods for handlingthis diversity. This is needed because, for example, if geographicallydistributed temperature data is to be gathered, then only electronicdevices 440 with temperature sensors 480 can be used to gather the data.The system can include a single computer server 410.

The present invention provides four modes for the system 400 shown inFIG. 7 to collect geographically distributed data: (1) gatheringgeographically distributed data in a server-commanded mode, accomplishedby a computer server 410 commanding electronic devices 440 to captureand transmit data, such that the user of the electronic device 440 neednot participate in the capturing or transmitting, and is, thereforetransparent to the user; (2) collecting user responses in aserver-initiated mode, accomplished by a computer server 410 requestingthe user of an electronic device 440 to input data, the data thentransmitted to the server 410; (3) supplying geographically distributeddata in a user-initiated mode, accomplished by a user capturing datawith an electronic device 440, the electronic device 440 transmittingthe data to a computer server 410, and the computer server 410 thenstoring, selling, or publishing the data; and (4) supplyinggeographically distributed data in a user-controlled mode, accomplishedby a user enabling his electronic device 440 to automatically capturedata, the electronic device 440 transmitting the data to a computerserver 410, and the computer server 410 then storing or processing thedata.

Mode 1: Gathering Data in Server-Commanded Mode

The first mode, gathering a body of geographically distributed data in aserver-commanded mode, is useful for situations where the user of theelectronic device 440 need not be bothered to respond. For example,assuming there are thousands of users with electronic devices 440 intheir cars as they commute to work (with the electronic devices 440turned on, enabled to participate in the gather of data, and equippedwith a GPS), a computer server 410 can query all the electronic devices440 for location and speed in order to generate a overall picture oftraffic conditions. This overall picture could then be sent to theusers, published on the Internet, or broadcast on television or radio.Similarly, temperature, sound, and even seismic activity could begathered this way.

FIG. 8 shows a flow diagram for an embodiment of the method forgathering data in a server-commanded manner. The system 400 awaits 501,503 a request to gather geographically distributed data. Continuing withthe above traffic example, a radio station could make the request of thesystem 400 to determine the traffic status so it can be reported on theradio.

The system 400 needs to query enough of the electronic devices 440 tofulfill the overall request for data; which could mean querying everyelectronic device 440 in the system 400, or it could mean querying onlyenough to reach a particular objective (e.g., are there at least fiftycars traveling at more than one hundred miles per hour on TelegraphRoad).

The computer servers maintain a list of electronic devices 440 that areturned on and enabled to receive commands. Hereinafter, this list iscalled the active device list, and it will be described later in thisdocument as FIG. 12. A server 410 selects 505 an electronic device 440from the active device list and begins communicating with it 440. If550, 560, 570 the selected electronic device 440 is not appropriate forgathering the data, the process skips to the next electronic device 440.The server 410 sends 507 a command to the selected electronic device 440for it 440 to capture one or more specific types of data. The selectedelectronic device 440 receives 509 the command and captures 511 thedata. The selected electronic device 440 transmits 513 the data to theserver 440, where it is received 515. An important, but optional, stepis the verification 517 of the identity of the electronic device 440,and this verification 517 can occur at almost any point during thecommunication between the server 410 and the selected electronic device440. After receiving 515 the data, the server 410 stores and/orprocesses 519 the received data. Another important, but optional, stepis the crediting 521 of an account corresponding to the selectedelectronic device 440. This crediting 521 gives the user of theelectronic device 440 an incentive to leave the device on and enabled toreceive data gathering commands. The credit can be any combination ofmoney, award points (redeemable, like frequent flier miles), ordiscounts on merchandise. The electronic device 440 can keep track of auser's account balance, in addition to the server 410. The server 410then selects 505 a next electronic device 440 if 523 another device isavailable or needed.

FIG. 8 shows the process of querying electronic devices 440 as a serialprocess, but this is only for ease of illustration. Commands to capture507 data can be sent to multiple electronic devices 440, so thatmultiple commands are “in flight” simultaneously. This allows sending ofcommands 507 and receiving 515 data to be interleaved across multipleelectronic devices 440. Another reason for interleaving commands 507 isto account for some electronic devices 440 not responding due to, forexample, power failure and communication link outages (common with cellphone technology). When a device does not respond to a server 410command 507, the server 410 detects this by detecting a “time-out”condition. That is, the electronic device 440 took too long to respond.Because this might be a common occurrence, it would be highlydisadvantageous to query electronic devices 440 in a purely sequentialfashion, because, a time-out condition would suspend the entire process.

FIG. 9 shows one embodiment for the decision 550 to skip a selectedelectronic device 440. The figure assumes a selected electronic device440 is always interrogated as to the types of geographically distributeddata it 440 can capture, the interrogation occurring prior to each timethe electronic device 440 is commanded 507 to capture data. The server410 commands 551 the selected electronic device 440 to transmit thetypes of data it can capture. The selected electronic device 440determines 553 the types of data it 440 can capture and transmits 554the types to the server 410 where it is received 555. The servercompares 557 the received types to the data types that need to becaptured. If 559 the comparison 557 indicates the selected electronicdevice 440 can not capture the needed data, that electronic device 440is skipped. Alternatively, the electronic device 440 could be sent thedata types that are needed, the comparison 557 could be performed in theelectronic device 440, and the electronic device 440 could reply with anindication as to whether it can capture the needed data.

FIG. 10 shows a second embodiment for the decision 560 to skip aselected electronic device 440. The figure assumes a server 410 storesthe types of geographically distributed data that each electronic device440 can capture. This list of types for each electronic device 440 canbe included in the active device list or kept as a separate list. Aserver 440 retrieves 561 the stored types of data the selectedelectronic device 440 can capture, and compares 563 this to the datatypes that need to be captured. If 565 the comparison 563 indicates theselected electronic device 440 can not capture the needed data, thatelectronic device 440 is skipped.

FIG. 11 shows a third embodiment for the decision 570 to skip a selectedelectronic device 440. FIG. 11 is an expansion of the method shown inFIG. 10 because it adds the constraint that the selected electronicdevice 440 needs to be located within a predefined geographic area.Hence, FIG. 11 includes the steps 561, 563, and 565 from FIG. 10. FIG.11 adds the steps of: the server 410 commanding 576 the electronicdevice 440 to transmit its location; the electronic device 440transmitting 577 its location; and a decision 579 to skip the selectedelectronic device 440 based on whether it is located within thepredetermined geographic area. The geographic area need not be spatiallycontiguous (it could be “any McDonald's restaurant”). Similarly, theconstraint of the selected electronic device 440 needing to be locatedwithin a predefined geographic area can be added to the methodillustrated in FIG. 9.

FIG. 12 illustrates an embodiment for the method of maintaining theactive device list. The figure shows how an electronic device 440 causesitself to be added or deleted from the active device list dependent onthe users wishes and whether it has its power on. In this figure,“start” 601 is where the electronic device 440 executes the method whenit is powered on. If 603 the electronic device 440 is set to beautomatically added to the active device list when it is powered on, theelectronic device 440 transmits 605 its identification to the server410, along with the types of data it can capture (the data types it cancapture are not sent if this data is not stored at a server 410, as inmethod 550), and the server 410 adds 607 this electronic device 440 tothe active device list and stores 609 the data types the electronicdevice 440 can capture. The electronic device 440 then waits for eitherthe user to command the electronic device 440 to turn off 611 or theuser to command the electronic device 440 to be removed 613 from theactive device list. If 603 the electronic device 440 is not set to beautomatically added to the active device list, it 440 waits for eitherthe user to command the electronic device 440 to turn off 615 or theuser to command the electronic device 440 to be added 617 to the activedevice list. If 611 the user commands the electronic device 440 to turnoff, the electronic device notifies 619 the server 410 to remove it fromthe active device list, the server does that 621, and the electronicdevice 440 turns off 623. If 613 the user commands the electronic device440 to be removed from the active device list, the electronic devicenotifies 625 the server 410 to remove it from the active device list,the server does that 627, and then the electronic device 440 waits foreither the user to command the electronic device 440 to turn off 615 orthe user to command the electronic device 440 to be added 617 to theactive device list. From FIG. 12, it is seen that the electronic device440 resides in one of two states: (1) being included in the activedevice list and waiting for either the user to command the electronicdevice 440 to turn off 611 or the user to command the electronic device440 to be removed 613 from the active device list; or (2) being notincluded in the active device list and waiting for either the user tocommand the electronic device 440 to turn off 615 or the user to commandthe electronic device 440 to be removed 617 from the active device list.The other steps in the figure are for transitions between these twostates. In addition to these steps, the types of data the electronicdevice 440 can capture should be updated whenever the user changes theinput/output devices that are attached.

In addition to the steps described above, encrypting any transmitteddata can be done so as to keep it private.

Mode 2: Collecting Data in Server-Initiated Mode

The second mode, collecting user responses in a server-initiated mode,is useful for situations where input from the user is desired. Forexample, marketing surveys can be performed where it is up to the useras to whether he will respond. A particularly useful example is therequesting of opinions based on geographic location. For example, theuser could be surveyed when leaving a particular type of restaurant(such as McDonald's) as to his experiences. Similarly, a survey could betaken of users located at a particular sporting event (such as the SuperBowl). These surveys could be accompanied by a sales pitch for aparticular company or product. If a user participated in a surveycollecting responses from people who just ate at McDonald's, anadvertisement or coupon for Burger King could be sent to the user if hissurvey indicated any dissatisfaction. Hence, marketing data and salescould be done in a distributed fashion.

FIG. 13 shows a flow diagram for collecting user responses in aserver-initiated manner. The system 400 awaits 501, 503 a request togather user responses. Continuing with the above restaurant example, acontinuous polling could be done to detect when a user exits the targetrestaurant. Or, a market survey company could request all users torespond to a particular survey.

The system 400 needs to query enough of the electronic devices 440 tofulfill the overall request for data; which could mean querying everyelectronic device 440 in the system 400, or it could mean querying onlyenough to reach a particular objective (e.g., query at least 100 peopleleaving McDonald's).

The computer servers maintain an active device list, as described above.A server 410 selects 703 an electronic device 440 from the active devicelist and begins communicating with it 440. If 705 the selectedelectronic device 440 is not appropriate for gathering the data, theprocess skips to the next electronic device 440 (in a similar manner tothe methods 550, 560, or 570). The server 410 sends 707 information tothe selected electronic device 440, the information soliciting aresponse from the user. The selected electronic device 440 receives 709the information and notifies 711 the user. The selected electronicdevice 440 waits for the user to either review or discard 713 theinformation, and if the user responds, the electronic device 440receives 715 the response and transmits 717 it to the server 410. Theserver 410 receives 719 the user response and stores or processes 721the user response. An important, but optional, step is the verificationof the identity of the electronic device 440, and this verification canoccur at almost any point during the communication between the server410 and the selected electronic device 440. Another important, butoptional, step is the crediting 723 of an account corresponding to theselected electronic device 440. This crediting 723 gives the user of theelectronic device 440 an incentive to participate in the collecting ofuser responses. The credit can be any combination of money, award points(redeemable, like frequent flier miles), or discounts on merchandise.The electronic device 440 can keep track of a user's account balance, inaddition to the server 410. The server 410 then selects 703 a nextelectronic device 440 if 725 another device is available or needed.

As an alternative to the steps of FIG. 13, the server 410 may transmit arequest of the user to respond and only send a small portion of theinformation to which he will respond (as a hint for what the survey isabout). Then, when the user indicates he wishes to review all theinformation, the rest is transmitted. This alternate approach can savebandwidth usage over the wireless communications network.

FIG. 13 shows the process of querying electronic devices 440 as a serialprocess, but this is only for ease of illustration. Just as describedabove, commands and data transmission can be interleaved. This isparticularly important in FIG. 13 because a user may take a long time torespond, and, in fact, may never respond.

As described above, encrypting of transmitted data can be done.

Mode 3: Supplying Data in User-Initiated Mode

The third mode, supplying geographically distributed data in auser-initiated mode, is useful for situations where the user of theelectronic device 440 wants to capture data that is local to him anddistribute it to a wider audience. For example, the user of anelectronic device 440 could be the witness of an accident, and use hiselectronic device 440 to capture video images (assuming the electronicdevice 440 includes a video capture mechanism), upload them immediatelyto a computer server 410, and then the computer server 410 candistribute or publish the video images as necessary. This mode ofoperation makes the user of an electronic device 440 a roving reporter.The invention also includes methods for reviewing the submitted databefore it is distributed or published. The review is important to filterout inappropriate, uninteresting, and redundant news.

FIG. 14 shows a flow diagram for supplying geographically distributeddata in a user-initiated manner. The user commands 803 the electronicdevice 440 to capture and transmit data, generally something of interestto someone other than himself. The electronic device 440 captures 805and transmits 807 the data. The server 410 receives 809 and stores 811the data. An important, but optional, step is the verification 813 ofthe identity of the electronic device 440, and this verification 813 canoccur at almost any point during the communication between the server410 and the electronic device 440. Another important, but optional, stepis the crediting 815 of an account corresponding to the electronicdevice 440. This crediting 815 gives the user of the electronic device440 an incentive to supply geographically distributed data. Once thedata is received 811, if 900 it is to be published, it is published 853,possibly on the Internet, television, or radio. Generally, a server 410credits 855 an account corresponding to the electronic device as areward for supplying data worthy of being published. If 861 the receiveddata is to be offered for sale 863, each time 865 the received data ispurchased, a server 410 credits 855 an account corresponding to theelectronic device 440. The data can also be offered for free 871, 873.

The present invention also includes a method 900 for editors to reviewdata before it is published or offered for sale, as shown in FIG. 15.The data received 811 by the server 410 is made accessible 901 to a setof editors. This 901 can be done by granting electronic access to thedata as it resides on a server, and such access should be passwordprotected. A signal is sent 903 to each editor, which can be done viaemail or by sending a command to an editor's electronic device 440.However, the editors can use any type of computing device, such asdesktop computers and laptops. One or more of the editors review, alter,and/or approve 905 the received data for publishing, and the server 410credits 907 their accounts appropriately. If 909 the consensus of theeditors is to publish the data, then it will be published 853. Similareditor review methods can be applied to the sale decision 861 and thefree availability decision 871.

Mode 4: Supplying Data in User-Controlled Mode

The gathering a body of geographically distributed data in auser-controlled mode is useful for situations where the user of theelectronic device 440 does not directly participate in the gather ofdata, but has the electronic device automatically transmit the gathereddata without receiving a command from the server 410. In other words,the electronic device 440 periodically captures data withoutintervention from the user. As seen in FIG. 16, the electronic device440 recognizes whether the user has enabled 950 or disabled 953 thegathering of data. The user can also select the types of data he wishesto transmit and the time of day or periodicity of transmissions. Theelectronic device 440 has a timer set so as to cause the capturing ofdata. When it is time to capture data 955, the electronic device 440captures 957 the types of data as selected by the user. The electronicdevice 440 transmits 959 the captured data to the server 410, and theserver 410 receives 961 the captured data. The server 410 verifies 963the identity of the transmitting electronic device, and stores orprocesses 965 the received data. The server 410 credits 967 value to anaccount corresponding to the transmitting electronic device.

Collecting and Transmitting Data

In all the modes, the transmitted data can be encrypted. This providesprivacy to the user.

In all four of the above described modes of collecting geographicallydistributed data, the type of can be one or more of the following:position, velocity, acceleration, temperature, altitude, air pressure,direction, audio, video, still pictures, vibration, and time of day. Inaddition to these, any other type of data that can be captured by acomputer can be collected by the above methods.
